Q value problem
When I do a probe test for my inductor(formed by two metal layer and a via trench), it seems that the Q value is much lower than HFSS result and the L value is normal, the most critical thing is the peak Q freq shift from 4G of simulation to 1.7G of test, what will cause that?
PS: the inductor is about 600 pH and the metal width is about 60 um
